Cyclopentamethylenedimethylsilane CAS 4040-74-8 chemical structure

Description

Cyclopentamethylenedimethylsilane (CAS 4040-74-8) is a high-purity analytical reference standard with the molecular formula C7H16Si and a molecular weight of 128.29 g/mol.

Cyclopentamethylenedimethylsilane (C7H16Si) contains an organic framework. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
